random number generator


Definition: See pseudo-random number generator.

Also known as RNG.

Note: Any computer program is likely to generate pseudo-random numbers, not actually random numbers. This is important when, say, simulations are sensitive to subtle patterns in the "random" numbers or security depends on the numbers being unpredictable.
